why do you say that? I truly want to know why I should pick LibreOffice over OpenOffice, or on Mac NeoOffice
- MS Office compatibility, which Libreoffice invests heavily in.
- Security: from what I remember OpenOffice struggled to ship fixes to various security issues in the past years. Meanwhile LibreOffice invest quite a bit: they're able to ship security fixes fast, and have spent time fuzzing and otherwise hardening code.
- Support: if you want commercial support, LibreOffice has that (not relevant for consumers, but important for enterprise).
OpenOffice hasn't even had a major release since 2014, only very rare point upgrades. That kind of cadence speaks for itself.
